This is my generator code:

$str = 'python -c "print(''a'');"'
$e = __(external $str read)

It is self-explanatory Smile
The result is that the program crashes: "Unhandled exceptions: Strings only store Characters"

For some other text than a, I get for $e a string of some Chinese signs. 

How to continue?

Goal was to generate a timestamp as such:

external 'python -c "from datetime import datetime; n =; print(n.strftime(''%d-%b-%H-%M-%S''));"' read 

and that also crashed, hence the investigation.

The python command isn't using the expected encoding for a command-line command, hence why MetaEdit+ shows an error (it shouldn't actually crash though - it just shows the error and you can press Terminate).

See if there are any options in python to change the encoding to match the command line's Unicode "cmd /u" (UCS-2 le). E.g." rel="nofollow - . If you can't figure it out on the Python side of things, you can simply have python write to a file with external...executeBlocking and then MetaEdit+ can read the file, specifying the encoding if necessary.
